Ling Yu's face changed again and again, his brows tightened for a while and then expanded, staring at the screen without saying a word.

The Fourth Fleet is subordinate to the Beiyue Continent Fleet, but the Mars plan is not implemented by the Northern Capital alone, and there are more than a dozen military attache representatives from the participating countries of the Mars program on the Nanzhou, and their faces are difficult to see.

According to the agreement reached between the countries, the impact will be broadcast live to the Earth throughout the process, but the distance between the Earth and Mars is a bit far, and it will take a little time for the direct signal to fly to the Earth.

Although it is not an open global live broadcast, there are not a few high-level people from various countries who watch the live broadcast, whether it is Ling Yu or military attaches of various countries, they don't know how to explain to their own high-level officials.

In fact, there is nothing to explain, Ling Yu's command is decent, although there is a little accident in the middle, but the stone mountain weighing hundreds of thousands of tons has hit Europin several times, from this point of view, the Mars program is undoubtedly successful, but who would have thought that even an astronomical-level impact could not help Ganymede?

The nuclear explosion is over, the interval between the two lava lakes is destroyed by the explosion, and the hot lava merges with each other, but the boundaries of the lava lakes have stabilized, and it is only a matter of time before the wounds heal.

Europa was still moving away from Mars, and a few minutes later, Wang Tianyu broke the silence: "The target has stopped changing direction and is calculating the target's orbit!" ”

Ling Yu sighed in frustration: "What speed is Europa?" ”

"Forty-four kilometers per second."

"Minus more than half!" Ling Yu's eyes were filled with despair.

He had done his best, but this was the result.

"It's going down." Wang Tianyu said.

Ling Yu was stunned: "It's still falling?" What about Mars? ”

"It's still rising."

Ling Yu sighed bitterly: "It's better to hit Mars!" After that, he exhaled heavily, "Forget it, report it." ”

"This ...... Can't you just think of a way again? Wang Tianyu said embarrassedly.

He's a member of the fleet, he's a professional soldier, and at worst, he's a member of the human race, and in every sense of the word, there's a reason to kill Europa, but the reality is so ruthless.

He didn't know if he would have missed this opportunity and if there would be another one in the future.

Ling Yu sighed again: "Lao Wang, I understand what you mean, but it's all at this time, I have already thought of a way to come up with it, I really can't do it, do you have it?" ”

"Nope." Wang Tianyu's voice was low.

"What about you?" Ling Yu looked around.

No one spoke, including the dozen or so foreign military attachés who were proficient in Chinese.

"Report it." Ling Yu said softly, "Sooner or later, report it early, prepare early, maybe you can stop it." ”

Obstruct? With what block? Blow up the moon and continue to crash?

Everyone knows that Ling Yu is deceiving himself, but what else can he do now but comfort himself?

Wang Tianyu was silent, and compiled the execution process into a formal report and handed it to Ling Yu for review.

Ling Yu waved his hand: "Just send it." ”

The report was sent to the earth through a laser, and Ling Yu unbuckled his seat belt and floated: "It's all gone." After saying that, he floated out of the bridge.

Ye Han wanted to persuade but didn't know how, he opened his mouth but didn't spit out a word.

As the actual executor of the Mars program, he has always been in the bridge, but he adheres to the principle of seeing more and talking less, and has never spoken.

Wang Tianyu retracted his worried gaze: "Did you hear it?" The staff on duty stayed, and the others did what they wanted. ”

Everyone left the bridge in turn, and Wang Tianyu was about to leave, when he suddenly heard a crisp prompt sound.

Looking at the multifunction display, it turned out to be Callisto Zero's new orbit and was calculated.

Out of professional habits, Wang Tianyu dispelled the idea of leaving, and sat down to carefully study Europa's new orbit.

His knowledge in astronomy, like that of most officers, has only learned the surface, and he only understands the situation in the solar system, and it is common to encounter problems in calculating and calculating data, but after a long time of contact, he has found a little pattern, and when he sees Ganymede's new orbit, he instinctively feels that something is wrong.

Callisto does not fly directly to Earth, but obliquely to Earth's orbit, and if you draw an extension line according to the existing orbit, this arc-shaped extension line is exactly tangent to the Earth's orbit, with a total length of nearly two astronomical units, almost 300 million kilometers, and at Callisto's current speed, it will reach Earth's orbit in three months.

I don't have time to calculate the detailed time, but that's probably it.

But the problem is not here, the problem is that the Earth is not in that direction at all, and when Europa reaches the Earth's orbit after three months, the two planets are exactly on opposite sides of the Sun, and the positions are definitely asymmetrical, but the distance is wide.

Isn't Europa's target Earth? What are you flying that far? Or is the current orbit just a transition, and the aliens will readjust the orbit in the future?

Otherwise, the aliens plan to fly to the Earth's orbit first, and then use the speed advantage to catch up with the Earth...... Obviously, you can fly directly to Earth, aliens can't be stupid to this extent, right?

The more I looked at it, the more weird I felt, and Wang Tianyu had a cautious personality, even if he saw the clue, he didn't want to jump to a conclusion directly, and when he looked up, he happened to see Ye Han floating to the door, and immediately shouted: "Ye Han, come here!" ”

The hatch had already opened in front of Ye Han, and Ye Zhi shouted that he grabbed the upper edge of the hatch and pulled himself back: "Chief of Staff, you called me?" ”

"Come here!" Wang Tianyu beckoned, pointed to the screen and said, "Look, what do you think?" ”

Ye Han looked at it carefully for a while, and looked at Wang Tianyu suspiciously: "This direction is wrong, right?" ”

"I don't think it's right either, but I can't think of a reason." Wang Tianyu said.

"I don't have a clue either......" Halfway through the words, Ye Han was suddenly stunned.

Wang Tianyu found that Ye Han's expression was wrong, and his eyes couldn't help but light up: "What did you think of?" ”

Ye Han shook his head: "It's nothing, I think it's wrong." ”

"Where do you want to go, say it and study it!" Wang Tianyu said.

Ye Han tugged at the corners of his mouth: "I think of the First Fleet, when the fleet flew to Jupiter, Ganymede was very close to Jupiter, there were mountains and rivers on it, except for a circle smaller than the earth, the others were almost ......."

Wang Tianyu suddenly realized: "You mean that their target is not the earth, but the earth's orbit?" ”

This was a bit twisted, but Ye Han understood it and immediately nodded: "I think it's very possible, we thought about it before." ”

The meaning of the words is very simple, the Earth is located in the middle of the habitable zone of the solar system, which is the best position in the habitable zone, and the aliens have put Europa into orbit around the Earth, and it will not be long before the frozen planet will be revived in the warm sunlight and become a lush habitable planet again.
